Modes of Operation Chapter 10
S-curve Filter (Position Mode)
S-curve filter smooths the motion command in position mode. With this filter,
speed/acceleration can be continuous and jerk is reduced, and a smoother
mechanical operation can be achieved. If the load inertia increases, the operation
of the motor will be influenced by friction and inertia when it starts or stops
rotating. Setting a larger acceleration/deceleration constant of S-curve (TSL) and
acceleration/deceleration time (numbers 0…15) in ID312…ID327
(P5.020…P5.035) can increase the smoothness of operation. When the position
command source is pulse, its speed and angular acceleration are continuous, thus,
S-curve filter is not a must.
NOTE: Acceleration/deceleration time constant is set via ID143 (P1.036).
